Possible to run the same job with different trigger in quartz?

I am using the following code to create multiple triggers, and then binding all these triggers to one job. But it failed

 "org.quartz.ObjectAlreadyExistsException: Unable to store Job : 'Group.Job', because one already exists with this identification.
"


 for (SchedulerBean schedulerBean : schedulerList) {
            Trigger trigger = newTrigger()
                    .withIdentity("trigger_" + schedulerBean.getConnectorID())
                    .usingJobData("ID", schedulerBean.getConnectorID())
                    .withSchedule(cronSchedule(schedulerBean.crontab))
                    .forJob(job)
                    .build();
            sched.scheduleJob(job, trigger);
        }
  sched.start();

From the error I suspect the sched.scheduleJob(job, trigger); part tries to schedule the same job multiple times.

Try adding sched.addJob(job, true); before the for loop to add it only once (the 'true' is for replacing old job if exists), and inside the loop use sched.scheduleJob(trigger); instead of sched.scheduleJob(job, trigger);

The sched.scheduleJob(trigger); is able to add the trigger to the job since you specified it with the .forJob(job) property
